TWINE-MAKING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 495,469, dated April 18, 1893.

Application filed April 12, 1890. Serial No. 347,731. (No model.)

To all whom it may concern:

Be it known that 1, FREDERICK G. BECKER, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Twine-Makin g Machines, of which the following is a specification.

My invention relates to improvements in twine making machinesin which the spindle shaft which carries the spool is adapted to be removed or partially removed from the machine in order that the full spool may be removed and replaced by an empty one, and it consists in certain improvements by which the spindle shaft is prevented fromleaving the machine by accident or otherwise after the machine has been set in motion.

The object of my invention is to prevent accident to the machine or to the person of the operator. I attain these objects by means of the mechanism illustrated in the accompanying drawings, in which- Figure 1, is a front elevation of a twine making-machine with my invention applied thereto. In this figure a portion of the framework is broken away in order to show a part of the gearing. Fig. 2, is an end elevation of a twine making-machine and clearly illustrates my invention.

Similar letters referto similar parts throughout the several views.

In the drawings, A, represents the frame of the machine and in Fig. 1 has a portion broken away to show the gearing that drives the double threaded screw shaft, which in combination with the shifting arm J, imparts a reciprocating motion to the spindle D, which drives the spool G.

B, is a driving shaft mounted at one end of the machine with bearings secured to the frame work A, and is provided with belt Wheels P, and P P, is secured to the shaft and is its driver, while P is mounted loosely thereon and is adapted to receive the driving belt when it is desired to stop the machine. Upon shaft 13, is mounted a gear wheel I), which engages with pinion b and drives the counter shaft 13. Upon shaft B, are mounted pulleys F, F, and F which by means of belt connections with pulleys F F and F drive the various spindles as follows; pulley F, the spooling spindle D, pulley F, the spinning spindle E, and pulley F the twine retarding spindle C The twine spinning spindle E, is provided with bearin gs at its extreme ends as shown in Fig. 1; these bearing ends of spindle E, are made hollow, one end for the reception of the retarding spindle O and the other for the reciprocating spooling spindle D. Spoolin g spindle D, is also hollow and through it is passed the shaft 0, which supports the spool G. Shaft O, in addition to its bearing in spindle D, is supported at either end by bearings c, and c.

L, is a sliding latch mounted in vertical ways T. and T. upon the front end of the machine frame A, and is adapted when in position as shown in Fig. 1, to secure the shaft 0, in its place and prevent it from moving endwise; and when raised, it permits an endwise movement of the shaft so that the spool can be removed from the machine.

M, is a rock shaft provided with the handle n, and also with a bell-crank at one end; arm R, of the bell-crank is adapted to operate the belt shifting bar V, which has its ways secured to the frame A, and which is provided with depending arms or fingers P and P, for shifting the driving belt from the loose pulley onto the driver or the reverse.

Thus far this explanation is common to all spinning-machines of this type and is given here at length so that my improvement may be more clearly understood.

S, is a lever which has its fulcrum bearing U, mounted upon the frame of the machine. One end of lever S, is connected with sliding latch L by means of a wrist pin .9, projecting therefrom. The hole in lever S, for-thereception of wrist pin 5, is slightly elongated so as to permit the vertical movement of latch L, while lever S, swings upon its pivot. The opposite end of lever S, is connected with the bell-crank arm 0, by means of pitman O. The end of pitman 0, connecting with lever S is provided with a link bearingf, sliding upon wrist pin f, so that the movement of shaft M, to shift the driving belt from one pulley to the other may be effected without effectinga movement of the lever S.

The operation of my device is as follows: when the latch L, is raised, the spooling shaft 0, is moved endwise out between the vertical ways T, T. The spool G, is placed in the machine and the spooling shaft 0, returned as shown in Fig. 1. The latch L, then falls to its normal position and locks the shaft 0, in place. The twine or thread is then connected with the spool G, and the machine set in motion by moving the handle N,in the direction of the arrow, which causes the arm R, to move the slide V, and shift the driving belt from the loose pulley P onto the tight pulley .P'. This movement of handle N, also moves the pitman O, by means of arm 0, upward until the lower end of linkf, is in contact with wrist-pin f which causes lever S, to hold latch L, in its retaining position, while the driving belt remains upon the tight pulley. To remove the spool when full, the handle N, is moved in the opposite direction which returns the belt to the loose pulley, stops the machine and brings the upper end of linkf, in contact with the wrist-pin f, as shown in Fig. 2. The latch L, can then be raised and shaft 0, removed as described.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a twine making machine the combination with a spooling shaft, a latch for securing the spooling shaft in place, a bellcrank for operating the belt shifting slide, a lever pivotedly mounted upon the frame and having one end connected with the latch, a pitman having a link or sliding connection with the opposite end of the lever and connecting said lever with the bell-crank, whereby a movement of the bell-crank in one direction releases said latch and when moved in the opposite direction secures the latch in its retaining position, a belt shifting slide operated by the bell-crank and adapted to shift the driving belt, the tight and loose pulleys and the driving belt, substantially as and for the purpose set forth.

2. In a twine making machine, the combination with a spooling shaft, a latch for securing the spooling shaft in place and adapted to slide in vertical ways upon the frame, a lever pivotedly mounted upon the frame and havingoneendconnected with thelatch,abellcrank for starting and stopping the machine, a pitman provided with a link or slotted portion and connecting the latch controlling lever with an arm of the bell-crank, and aloeltshifting slide, sliding in ways upon the frame and operated by said bell-crank, substantially as and for the purpose set forth.

3. In a twine making machine, the combination with the spooling shaft, alatch for preventing an endwise movement of the spooling shaft and adapted to slide in vertical ways upon the frame, the shaft M, having the arm or lever N, and carrying at one end a bellcrank, a bell crank having arms R, and O, the arm R, adapted to operate the bell shifting slide, the arm 0, pivotedly attached to a pitman rod, said pitman rod having a sliding connection with lever S, the lever S, having its fulcrum bearing upon the machine frame and having its forward remaining end connected with the latch by means of a wrist-pin, the driving belt, the tight and loose pulleys mounted upon driving shaft 13, and the belt shifting slide, all substantially as shown and described.

In testimony whereof I affiX my signature in presence of two witnesses.

FREDERICK G. BECKER.
